Boring Books: Do You Finish Them?

I loved all of her other books (Sex and the City,Lipstick Jungle, Trading Up, etc.) but I just cannot get into this one.

I'm a little over halfway through and still think it's super lame. I want to just give up on it, but when I do it just sits on my bookshelf, taunting me and begging me to give it another chance. So I do, and after 30 minutes of reading, I'm yet again annoyed at how uninterested I am in it. Grr. I suppose I'll eventually finish it.

What do you do when you're in the middle of a book you just can't get into? Do you finish it or toss it aside mid-read? What are you reading right now?
